Description

In fire alarm system, such condition often occurs that partial short circuit of loop affects the whole system. DC-9503E Loop Isolator（hereinafter referred to as the isolator）can isolate the shorted circuit from the whole system to ensure normal operation of other devices and help locate the devices in fault. After the short circuit fault is cleared, those devices will be re-introduced into the system. The isolator is suitable for use in the loop of addressable fire alarm system.
